Choose true or false for each statement regarding concave
mirrors.
true false If an object is placed 4.1 cm from a concave
mirror with f = 4 cm, then its image will be enlarged and
real.
true false A concave mirror produces an enlarged real
image when the object is placed just beyond its focal point (Region
2).
true false If an object is placed 7.9 cm from a concave
mirror with f = 4 cm, then its image will be enlarged and real.

Choose true or false for each statement regarding convex
mirrors.
true false If an object is placed 7.9 cm from a convex
mirror with f = 4 cm, then its image will be reduced and
real.
true false A convex mirror produces a reduced real image
when the object is placed far beyond its focal point (Region
1).
true false If an object is placed 4.1 cm from a convex
mirror with f = 4 cm, then its image will be reduced and real.

Choose true or false for each statement regarding the sign
conventions for mirrors.
true false Virtual images appear behind a mirror and
have a positive value for the image distance.
true false The magnification m is positive for inverted
images.
true false The magnification m is negative for upright
images.
1) If an object is placed 4.1 cm from a concave mirror with f = 4 cm, then its image will be enlarged and real. (True)
Reason: The closer the object comes to the focal point (without passing it), the bigger the image will be and real also.
2) True.
3) If an object is placed 7.9 cm from a concave mirror with f = 4 cm, then its image will be real but not enlarge.
4) If an object is placed 7.9 cm from a convex mirror with f = 4 cm, then its image will be reduced and virtual.
5) A convex mirror produces a reduced virtual image when the object is placed far beyond its focal point
6) If an object is placed 4.1 cm from a convex mirror with f = 4 cm, then its image will be virtual.
7) Virtual images appear behind a mirror and have a positive value for the image distance (True)
8) The magnification m is positive for inverted images (False)
9) The magnification m is negative for upright images.(false)
